The distance in the width direction between the optical axes of the two lenses is larger than these, and the distance in the width direction between the optical axes of the two lenses is
This value is such that the light rays from the left and right images exiting from these lenses become almost parallel at the junction between the two lenses, so that the user does not have to shift his or her eyes when looking toward the lenses. , and the lens has an optical wedge-shaped body that bends the image seen by the user so as to spread outward in the front direction of the lens, and the orientation from the stereo image to the lens is A stereoscopic mirror that is characterized by being presented as a single continuum. (2) The stereoscopic mirror according to claim 1, wherein the lens is a Fresnel lens. (3) The stereoscopic mirror according to claim 1 or 2, wherein the pair of stereo images is a pair of photographs, and further comprising means for providing the stereo image at a predetermined position behind the lens. (4) The stereoscopic mirror according to claim 1 or 2, further comprising distance detection means for a user to position the stereo image at a desired position behind the lens. (5) The stereoscopic mirror according to claim 4, wherein the distance detecting means includes a pair of prisms that intersect with each other and are arranged so that the center points of the left and right images appear to coincide when they are at a desired position. (6) The stereoscopic mirror according to claim 5, wherein the prism is integrally molded with the lens.
